To all whom t may concern."

Be it known that HENRY M. VILLIs, de ceased, who was a citizen of the United States and resided in the village of Hempstead, town of Hempstead, county of Nassau,

whereby the nicotin and other poisonous,

substances in tobacco cannot penetrate the stem of the bowl; to provide means whereby the stem of the bowl is prevented from becoming soakech thus avoiding the nauseous and foul smells which emanate from the average pipe after it has been used; to provide means whereby the smoke and heat, in its passage to the mouth-piece from the bowl of the pipe, are prevented from flowing in such volume as to sting or burn the tongue; to provide means whereby the smoke and heat, in transit from the bowl to the mouth-` piece, are cooled; to provide a false or removable bottom for the bowl of the pipe of a nonabsorbent material; and to provide means whereby the stem and bowl of the pipe may be readily cleaned and the moisture usually condensed in the bottom of the bowl and the bottom of the stem of the pipe can be quickly and thoroughly removed.

With the above objects in view, and others which will be pointed out during the course of this description, the invention consists in the parts, features, elements and combinations of elements herein rdescribed and claimed.

Referringfto the drawings: Figure l is a longitudinal, vertical section of a pipe embodying the invention; Fig. 2 is a vcross-section on the line 2-2 of Fig. l, the section being, however, of the entire pipe-stem; Fig. 3 is a vertical, longitudinal section of a pipebowl and stem showing the invention applied`J thereto; Fig. a is a perspective view of the combined plug, moisture-collector and smoke-divider; Fig. 5 is a View similar to Fig. 3, showing another form of the invention; Fig. 6 is a cross-section on the line 6 6 of Fig. 5; and Fig. 7 is a View similar .to Fig. 3, showing still another form of the invention.

Referring to the drawings, the numeral l indicates the bowl of the pipe, 2 the stem thereof, 3 the brace or binder on the end of the stem, et the mouth-piece, 5 the false, non-absorbent bottom or lining for the stem and bowl of the pipe and 6-the combined plug, moisturecollector and smoke-divider.

As shown in Fig. l, the bottom of the bowl, instead of terminating in a small hole at the juncture of the stem with the bowl, is very much enlarged, as indicated at 7, the opening at this point, in fact, being a continuation of the inner walls of the bowl clear down to the bottom thickness 8 of the pipe, thus making the opening of the bowl of the pipe extend substantially uniformly from top to bottom and enabling the tobacco, when inserted in the bowl, to rest clear down upon the lining or false bottom 5, and upon the device The passage in the stem 2 extends or merges into the bowl-opening 7 and continueson through the base of the bowl to the outside thereof, as clearly shown in the several gures. The false bottom or lining 5 extends from the outside of the base of the bowl to substantially the point 9 in the stem, leaving between the end of said lining and the inner end of the mouth-piece l a chamber l0, in which the smoke may collect primarily, and the heated air can expand and cool to a considerable degree.

Referring, particularly, to Figs. 3 and t, it will be seen thatthe device 6 has an enlarged, concavo-convex head 11, at the outer end of its U-shaped stem, the inner end of said stem being upwardly curved so as to provide a frictional holding-prong 12, which overlies the lgroove 13 insaid stem. The device 6 is forced, as shown in Fig. l, into the tubular lining 5 of the stem, at the inner end of which the prong 12 will securely hold 4the same against accidental removal, it requiring, in point of fact, considerable of a pull to remove the device 6 from the stem of the pipe by forcing the finger-nail under the head 11 thereof. Inserted as thus described, the device 6 has its slot 13 open upwardly so as to receive in its U-shaped stem the bottom-portion of the tobacco-wad inserted in the bowl of the pipe and so as also to receive, collect and hold all moisture, juices and acids which are usually condensed during the burning of the tobacco. Furthermore, as the smoke and heated air are drawn through the stem into -the mouthpiece, they are separated or divided by thi` curved end-prong 12, so as to flow into the chamber 10 in narrow columns or streams, the heated air, in such chamber, expanding and cooling very materially before entering into the passage 1A of the mouth-piece 4. The lining or false bottom of the stem and bowl is made of any material which is noncorrosive and non-absorbent, such, for example, as aluminum, the same thus preventing the pipe-bowl and stem from absorbing the juices and other moisture condensed from the tobacco and thus avoiding the steeping of the pipe with nicotin and the usual fouling of the pipe, resulting therefrom.

As shown in Figs. 1 and 3, the lining 5 is tubular from end to end and has its top and sides cut away in conformity with the shape of the bowl of the pipe and so as to continue the form and shape of the latter down into the stem 2. Vhen it is desired to clean the pipe, it is only necessary to insert the lingernail under the head 11 and thus remove the device 6, which will bring with it all the moisture collected therein, together with such portions of the charred tobacco as have not been removed by rst knocking the pipe. It will be understood that, in outline, the device 6 conforms to and snugly fits the inner surface of the lining 5, see Fig. 2; but, if any moisture has condensed upon the upper portion of the lining 5, it can readily be blown, washed or wiped out through the bowl-end of the passage in the stem 2.

In the form of the invention shown in Fig. 5, the device 6 is omitted, together with the complemental structure of the bowl and stem of the pipe; but, the non-absorbent, non-corrosive lining 15 is extended to the outermost portion of the bottom of the bowl of the pipe, as at 16, so as to receive the tobacco and moisture as described with reference to the form of Fig. 1. 'Ihe forward end of the lining 15 is provided with a circular screen 17, as clearly shown in Fig. 6, having the function of dividing the smoke and heat as it leaves the lining 15 and enters the chamber 10.

In the form of the invention shown in Fig. 7, the pipe is made substantially the same as in Fig. 1, but the false bottom or lining 18 is extended not quite so far along the stem 2 of the pipe and has on its outer end the head 19, formed integral with it, whereby, by inserting the nail under the head 19, the lining and false bottom of the pipe-bowl can be removed. Bv thus forming the lining, the expansion-chamber 10 is continued, as at 20, along the stem of the pipe to the lining 1S.

Vith the above detail description, the mode of operation, functions and advantages of the construction will need no amplification, except in so far as may be indicated by the scope of the annexed claims.

Having thus described the invention, what Iy claim and desire to secure by Letters Patent is:

1. A pipe having the bottom of its bowl extending clear into its stem and of substantially uniform diameter throughout, in combination with a lining for said stem of non-absorbent material, said lining conforming to the shape of the stem of the pipe and continuing the bottom of said bowl to the bottom of said stem.

2. A pipe having a bowl o f substantially uniform diameter from top to bottom and extending into its stem, a moisture-collecting` device in said stem into which the bowlbottom extends, and means carried by said device and engaging the inside of said stem for retaining the device in place.

3. A pipe having a bowl and a stem, said bowl being of substantially uniform diameter from top to bottom and having its bottom extended clear to the bottom of said stem; in combination with a lining of nonabsorbent material in said stem having a portion extended under said bowl and for-ming the bottom thereof; and a combined plug and moisture-collector in said lining.

4l. A pipe having a bowl .and a stem, said bowl being of substantially uniform diameter from top to bottom and having its bottom extended clear to the bottom of said stem; in combination with a lining of nonabsorbent material in said stem having a portion extended under said bowl and forming the bottom thereof; a combined plug and inoisture-collector in said lining; and means for dividing the volume of smoke as it traverses the stem.
